How this calculator works
Enter the bill, pick a tip percentage, and set how many people are splitting. The calculator shows the tip, the grand total, and what each person owes — and the share button copies a link with the exact numbers, which is the fastest way to settle who pays what at the table.
In the US, 15–20% is customary at sit-down restaurants, with 18% a common middle ground. In much of Europe service is included and rounding up is enough; when in doubt, check the bill for a service charge before adding more.
The formulas
Tip = bill × (tip% ÷ 100)Total = bill + tipPer person = total ÷ number of peopleWorked example
- Bill $85.50, tip 20%, four people.
- Tip: 85.50 × 0.20 = $17.10.
- Total: 85.50 + 17.10 = $102.60.
- Each pays 102.60 ÷ 4 = $25.65.
Frequently asked questions
Should I tip on the pre-tax or post-tax amount?
Convention in the US is the pre-tax amount, though many people simply tip on the total for simplicity — on a typical 8% tax the difference is small.
Is the tip already included sometimes?
Yes — many restaurants add an automatic gratuity (often 18–20%) for parties of six or more, and some cities add service charges. Check the bill before tipping twice.
How much should I tip for delivery or takeout?
Common US practice: 10–15% for delivery (more in bad weather), and no obligation for counter takeout, though rounding up is appreciated.
How do I figure out what percentage I actually tipped if I already know the dollar amount?
Rearrange this calculator's formula: tip percentage = (tip amount ÷ bill) × 100. For example, leaving a $17.10 tip on an $85.50 bill works out to (17.10 ÷ 85.50) × 100 = 20%, the same numbers as the worked example above in reverse.
How do I split an uneven bill fairly?
Either split the total evenly — what this calculator does — or have each person pay their own items plus their proportional share of tip and tax. Even splits are simpler; itemized is fairer when orders differ a lot.
